## What is 1213Buy 1to1FlashBuy?

Turn your iPhone into a pop-up shop that serves one customer at a time.

1213Buy is a mobile one-to-one pop-up shop platform. Merchants open a shop, manage products, and serve customers directly from their phone. Customers browse, join a queue, and get invited into a private session, like walking into a store that opens just for you.

Not a mass marketplace. Not a livestream. Just a focused, personal shopping experience.

FOR MERCHANTS

- Open fast: name your shop, pick a category (handmade, fashion, art, collectibles, lifestyle, secondhand), write an intro, and be instantly discoverable
- Product catalog: add items with photos, prices, and stock; run timed flash sales
- Queue management: see who is waiting in real time and invite the next customer with one tap; no-shows are skipped automatically
- One-on-one sessions: text chat and voice calls, share your catalog live, and let customers add items to the cart
- Trade confirmation: both sides sign a record listing items and quantities, stored on both devices
- Broadcast messages: notify everyone in the queue, such as opening soon, flash sale on, or back in a moment
- Reservations: approve or decline item hold requests with a time limit

MERCHANT-FRIENDLY PRICING

- Your first 180 days are completely free, with every merchant feature unlocked and no subscription needed
- After the free period, you can still open your shop free for 1 hour every day
- Subscribe monthly or yearly only when you need longer opening hours
- Cancel anytime in Settings; access continues through the paid period

FOR CUSTOMERS

- Discover pop-up shops by category or keyword, and save your favorites
- Join a queue anonymously, see live queue counts, and get notified when it is your turn
- Enter a private session with one tap: chat, talk, browse the catalog, request holds
- Confirm trades with items and quantities, e-signed by both sides and saved on your device
- Always free: customers never need a subscription

SAFETY AND PRIVACY

- Anonymous queuing: customers use a chosen alias, and merchants never see your real identity
- Report and block any shop in one step, with screenshot evidence supported
- Prohibited items policy: illegal goods are explicitly banned, see the full policy in the app
- Product data stays on the merchant device and is never uploaded to the cloud

1213Buy is a communication tool, not a payment processor. All transactions are arranged directly between merchant and customer.
